Installing the auto-tuner on your bike

Once you have chosen the best auto-tuner for your Harley Davidson, the next step is to install it on your bike. This process will vary depending on the tuner you choose, so be sure to read the instructions carefully. Generally, you will need to remove the air cleaner cover and the fuel tank and then connect the tuner to the appropriate sensors and cables. Once installed, you will need to calibrate it to your bike by following the instructions provided.

Once your tuner is installed and calibrated, you are ready to ride! Be sure to take it easy at first – it may take some time to get used to how your bike runs with a tuner. But once you do, you will likely notice a big difference in how your Harley Davidson performs.

The Best Auto Tuner For Harley Davidson Buying Guide

When choosing the best auto-tuner for your Harley Davidson, there are a few things you need to consider. The first is what type of Harley you have – not all tuners work with all models. You also need to make sure that the tuner is compatible with your cam and fuel management system. Finally, you need to decide if a tuner is right for you – some riders find they don’t need one, while others find it makes a big difference in how their bike runs.


The best auto-tuner for your Harley will depend on the model you have. Some work with all models, while others only work with specific ones. You need to make sure that the tuner is compatible with your motorcycle before purchasing it. If you are unsure about this, contact the manufacturer or an authorized dealer who can help you determine which tuner is best for your bike.

Type of Tuner

Two types of Harley Davidson auto-tuners piggyback on the ECU and those that work independently. The first type is more common, and it relies on factory calibration to provide fuel and ignition maps. This type is typically less expensive and easier to install, although it also has limited adjustability.

The second type is more complex and requires you to reprogram the ECU completely. It is best for those who want complete control over their bike’s performance, but it does require some technical knowledge that the average rider may not have access to. This tuner is also more expensive and can be challenging to install.

Price Range

Auto-tuners for Harley Davidson motorcycles can range from $300 to over $1000. It is best to determine what you need your tuner to do and then look at the options within that range. The best auto-tuner for one rider may not be the best option for another – it all depends on your budget and what you expect from it.

State Emission Laws

Many states have emission laws that require you to pass an inspection every year. If your state does not have this requirement, it may be best to go with a tuner that allows you more options and adjustability. However, if your bike is registered in California or another state with these types of emission requirements, then you will want to stick with a tuner that meets those standards.

Wired or Wireless

Most Harley Davidson tuners are wired, meaning that you need to connect them directly to the bike’s sensors and ECU. This can be difficult if your motorcycle is not easy to access, but it does provide a more stable connection. Some wireless tuners are available, which do not require any wiring. These tend to be less expensive and easier to install, but they are best for bikes that do not put out a lot of power.

Installation Difficulty

The difficulty level will depend on the type of Harley Davidson tuner you choose. Some require that you remove parts or wires from your bike, while others can be installed quickly and easily. It is best to go with a tuner that fits your skill level, so you do not end up damaging anything or making the installation harder than it needs to be.

Warranty & Return Policy

You want to make sure that any Harley Davidson auto-tuner you purchase comes with a warranty and return policy. Usually, this covers defective parts or damage caused during installation. It is best to check with the manufacturer or dealer before purchasing a tuner to ensure you are covered if something goes wrong.

Take care of your tuner to keep it in good condition

Just like any other piece of equipment, your auto-tuner needs to be taken care of to keep it in good condition. Be sure to keep it clean and free of debris, and check the cables and sensors for damage regularly. If you notice any problems, take your bike to a Harley Davidson dealer for repair.

Also, be sure to fuel up your bike properly. Using bad quality fuel can damage your tuner, as well as your bike. Always use high-quality fuel specifically designed for motorcycles.

By taking care of your auto-tuner and using quality fuel, you can keep it in good condition and enjoy the benefits it provides for many years to come!
